A2 m long column made of structural steel with elastic modulus of 200 GPa is loaded in axial compression. If the cross section of the column is a 20 mm by 50 mm rectangle, and one end is fixed and the other end is pinned, the maximum axial load that the column can bear before buckling, in kN, is (round to the nearest whole number)
A 3 m rigid bar AB is supported with a vertical translational spring at A and a pin at B The bar is subjected to a linearly varying distributed load with maximum intensity g Calculate the vertical deformation of the spring if the spring constant is 700 kN/m. (ans: 21.43 mm) 2. A steel cable with a nominal diameter of 25 mm is used in a construction yard to lift a bridge section weighing 38 kN. The cable has an...
